Excepxcional. Uso essa ferramenta há anos desde o Firefox. É útil para descobrir o css, visualizar as dimensões das imagens e ter acesso aos conteúdos mais difíceis dos site. Parabéns aos desenvolvedores!
Love this. Saved me a lot of time and headaches.
没什么用
amazing)
good!!
otimo
I wish it didn't show that pop-up after installing it. That appears each time I create my profile on a machine and restore my extensions (which is pretty frequent for me). Also it provided no use even on first install.
Great tool, I use it all the time.
respect...but wish more professional.
Rất hữu ích. Xin cảm ơn!
